#### ALPINE ONLY ####
# Alpine does not include the very common `glibc` GNU C Standard Library, which
# causes compatibility problems. Among other things, AWS CLI v2 does not work
# out of the box with Alpine. The following recipe installs `glibc` , and has to be run
# before installing other packages, particularly `libc6-compat`, and then,
# because it conflicts, you have to tweak a bit and then install `libc6-compat`.
# So put this in Dockerfile.alpine after setting up the package repositories
# but before installing any packages https://github.com/cloudposse/geodesic/blob/91336bf56fb7ff0d9812e01ceacc40ca59a17cce/os/alpine/Dockerfile.alpine#L81
